cargo publish error message unhelpful with publish = false

[wooorm]

$ cargo publish --dry-run
error: `xxxxxxxx` cannot be published.
The registry `crates-io` is not listed in the `publish` value in Cargo.toml.

It’s a bit stupid on my part, I forgot for a second that I had publish = false in my Cargo.toml to prevent publishing, but this error message threw me off.
I can imagine that some other folks would run into this too, so I’m raising this here.

How about an error message, if publish = false, along the lines of:

error: `xxxxxxxx` cannot be published.
`publish` is set to `false` in Cargo.toml and prevents publishing.

This error message is actually in Cargo: https://github.com/rust-lang/cargo/blob/3ff044334f0567ce1481c78603aeee7211b91623/src/cargo/ops/registry.rs#L140

Could you re-file this over in the Cargo repo please?

Good point, raised here: rust-lang/cargo#11262.
